A. Polycarbonate is supplied in sheets which are light weight. They are constructed of a two, three or five tier channel. This supplies an insulating effect which keeps the temperature more even and provides better growing conditions for your plants. They come in different thickness (4mm, 6mm,8 mm, etc.).
